Eaton Crouse-Hinds ECLK236 S758 Coupling - NEC/CEC
Part Number: ECLK236 S758
Quick Summary
Eaton Crouse-Hinds ECLK236 S758 is a 36-inch flexible coupling designed for hazardous locations. Field installations often struggle with rigid fittings that crack under stress or coatings that degrade in aggressive environments; this coupling combines forged brass with a flexible PVC protective coating to resist corrosion and vibration. It carries NEC/CEC standards and NEC hazard ratings for Class I, Division 1, along with UL listings for the US and Canada, ensuring regulatory peace of mind. This solution supports reliable, long-life explosionproof conduit connections while aligning with procurement goals and ongoing maintenance workflows.

Eaton Specification Sheet - ECLK236 S758
36-inch flexible length with a 3/4 inch trade size provides a long, continuous run that reduces joints and potential leakage points. This translates to faster installs, fewer field splices, and lower maintenance over the life of the system. Application: ideal for long conduit runs in chemical plants, refineries, or offshore facilities where strict hazard-location codes apply. Forged brass body with a flexible PVC protective coating delivers superior corrosion resistance and mechanical durability, reducing replacement cycles in aggressive environments. Application: offshore rigs and chemical processing plants where environmental exposure is high. Male connection on one end and female connection on the opposite end offers versatile, field-adaptable assembly, simplifying replacements and retrofits. Application: modular conduit networks and in-line splices in complex installations. Overall length of 40.13 inches and weight of 6.3 pounds provide clear planning data for mounting, support structures, and inventory management. Application: fits standard racking and cabinet spaces in industrial plants. Compliance with NEC/CEC standards and UL listings reinforces safety, inspection readiness, and procurement confidence. Application: projects with strict regulatory requirements and audited maintenance records.

FAQs
Prepare by confirming compatibility with a 3/4" trade size conduit and the 36" flexible section. Clean mating ends, align male and female connectors, and tighten to the recommended torque using approved fittings. Ensure the flexible coating remains intact and follow NEC/CEC guidelines for Hazardous Location installations. Perform a final inspection and verify UL-listed status and proper bonding/grounding per site standards.
Key specs include a 36-inch flexible length, an overall product length of 40.13 inches, 3/4-inch trade size, forged brass construction, and a flexible PVC protective coating. It features male and female ends on opposite sides, weighs about 6.3 pounds, and carries NEC/CEC certifications with Class I, Division 1 hazard ratings. UPC is 782274587769.
Yes. It is designed for hazardous locations and supports Class I Division 1 (with additional Class II/III coverage as applicable). The combination of forged brass, flexible coating, and explosionproof construction makes it well-suited for chemical processing, oil and gas facilities, and offshore installations where regulatory compliance and durability are critical.
The coupling adheres to NEC/CEC standards and NEC hazard ratings for hazardous locations. It is UL-listed for both the United States and Canada, with pages confirming explosionproof conformance for conduit fittings used in hazardous locations.
The forged brass body and PVC coating deliver enhanced corrosion resistance and mechanical durability, leading to longer service life and fewer field repairs. The 36-inch flexible section reduces joint count, improving installation speed and reliability, which translates to reduced downtime and lowers lifecycle maintenance costs.
